Answers:

   5. true

Explanation:4.

Paddles:
Current passes from one paddle through the patient's heart and is carried back by the second paddle, completing the circuit.
• Adult paddles are approx. 13 cm in diameter (avoids burns while allowing sufficient density of current at the applied site) 
• Requires a force of 10 Kg to be applied while pressing them onto the patient's chest (establishes good electrical contact between patient and paddles). 
• Pads should be applied parallel to the long axis of the heart.
